Hmmm. Interesting... I learn something new every day. Well, maybe
every other day...
I've seen the "divert to air cleaner", and "divert to underhood" methods
before, but never seen a "divert to manifold" setup. The only type I've
ever seen on an FE is of the "divert underhood" flavor.

Yeah, I guess that makes sense to dump the air into the intake under
deceleration to lean out the A/F ratio, but I've never seen (noticed) it
being done. I'll have to keep my eye out at the wreckers to see what it
looks like...
I'm pretty sure it was never done on the FE family and the poster of the
origional question about hooking up the thermactor system needen't worry
about coming up with a special intake manifold. It's the heads that are
going to make/break him. Hopefully his already have the bosses on the
exhaust port for the air injection tubes and he can drill them and press
a set of injection rails in. Otherwise he's gotta score some different
heads and swap 'em on... )-:

My '53 F100 has a 351C-4V and a C6 from a donor '71
Torino. While the engine has been rebuilt, the C6 sat
for quite a while before it was put back into
operation. I don't think there was a lot of mileage on
either unit, but I can't be sure. I know the tranny
needs a reseal job because it leaks a bit, as I
expected. However as I tool down the highway, I hear
quite a din from the tranny. It runs and shifts fine
but the noise worries me, am I on borrowed time with
this unit, should I look for a rebuild or replacement?

What years did this happen on the 351C ? I don't have that on mine (a '71,
I believe).

To all,
Today I finally got around to installing that Pertronix solid state ignition
with the Flamethrower on my '67 F100 with the 352. I must say, I do notice
much better idle and better response below 3000 rpms. I'd like to install
the MSD 6A capacitive discharge multi-spark module as well. Does anyone one
know if this is compatable with the Pertronix? Well my restoration is
comming to a close and soon I'll send pictures to Ken to put on the website.
This is a real headturner. By the way, is there any FTE'rs around the San
Diego area?

you are absolutely right it is a 400M. Sorry to add confusion to the mix.

>>and new speakers into the beloved vehicle. Gotta have my noise! (Thanks

I failed to keep the posting concerning shielding the speakers inside the
door, but I had made a hard copy for my PPUH (poor put upon husband).
Talented, huh? ;-)

So, allowing for my keyboarding, here goes:

"Try some Visqueen plastic between the speaker and the door. It's a cheap
fix for the wet speakers." wrote Smeck.

My PPUH says just the top edge of the plastic needs to be glued in place,
but I say seal the thing all the way around -- and use something like RTV
adhesive.

If your looking for the windshield gasket or the back glass gasket
you might find them less expensive at your local "glass shop." I
installed auto glass for 3 1/2 years and the quality of gaskets we used
were very high. (OEM or better) We used the "Precision Parts" brand,
which is very common through out the country in glass shops.
The cost varied for the gaskets depending upon which kind of trim
was used on the seal, such as: real chrome inserts, black or "fake
chrome" locking strip, or plain, with no locking strip. In other words
three types of windshield gaskets for 73-79 Fords.

Well, if the radio out of the Explorer is a DIN mount radio,
you're going to need to cut up some of the dash in your truck. It's not
real difficult, and if done right it looks pretty good. I've got a DIN
mount CD player in place of hte original shaft mount AM radio. Just take
your time and measure. You're going to need to cut the metal support that
holds the air conditioning/heater controls in place. You will also
probably need ot modify the plastic trim piece. If you have any specific
questions, email me and I'll do my best to answer them. Good luck with
the tunage!

Thank you John LaGrone for your reply. Yes I did add stop leak to the
cooling system and yes I did replace the radiator. (I'll give you two
guesses as to which order I did them in :) ) Every thing in the
system Is new except the heater core. (Still need to finish that
project.) So I guess that there still could be some in there. The
consensus seems to be that I don't have a problem no matter who had the
right answer.
